Success of Hybrid Perovskite Semiconductors Explained

Work by Chemical & Biomolecular Engineering graduate student Joe Manser has demonstrated, by pump-probe transient absorption spectroscopy, that photoexcited charges in a new class of semiconducting materials, organic-inorganic hybrid perovskites, exist in an inherently unbound state. Understanding the reasons for the success of these low-cost materials is essential for fully optimizing their performance in light-harvesting assemblies. link
